For the two that others are struggling with (column 1 row 3 and the last one on the bottom right) I've never heard of them. Definitely not as recognizable as the rest, to me at least.

I won't give away the answers but if you're like me and want to cheat just Google "Lego TV Characters" (I did a Google Image search) and you should be able to find the answers pretty quick. Those two are the only ones I didn't and couldn't recognize almost immediately.
